CASSIUS P. BYERS, OF VELVA, NORTH DAKOTA.

Specification of Letters Patent.

Patented June 29, 1909.

Application Iled April 1, 1908. Serial No. 424,546.

To all whom 'it may concern:

Be it known that I, Cassius P. Bricks, a l

citizen of the United States,

Velva, in the county of McHenry, State of North Dakota, have invented certain new In carrying out my invention, I inclose the upper end of the smoke stack within i: hood which is of two-part construction the lower half of the hood having spark conducting and collect-pipes extended from its lower end and provided :it their lower cnds with movable closures whereby the cindei's may be permitted 'to discharge from the pi es, the upper half of the hood being pro vi ed interioriy with on annular dellector the smaller end of which is located directly above the upper end of the smoke stuck. Suspended from the seid end of the deilector is an inverted conical foreininous deflecting element referiibly formed of wire mesh ino.- terial an this element projects downwardly into the u per end, of the steck. In the lower section ol) the hood'.l cre lorined openings which are covered by sheets of'wire mesh miiterial and similar openings or vents are formed in the upper section iibove the deilector, these openings aiding in the creation of a circulation within the stack.

In the accompanying drawings, Figure is e vertical sectional view through the upper end of e smoke stach constructed in aceordancewith in v iiivention. Fig. 2 is a siiniliir view but taken iii a plane at right angles to the plane oi' Fig'. l, l* ig. is zi top plan 'view of the stach, Fig. i is a horizontal section on the line l -4 oi' Fig. l. Fig'. 5 is a horizontal section on the line '5V-5 oi Fig. 1. Fi 6 is a horizontal section on the line @No of lig. 1. Fig. 7 is a detail in perspective of the up )er end ot' the stuck showing the cinder collectin and conducting pipes hereinafter referre to.

In the drawings, the stack proper indicated by the numeral 10 und is provided with un upper flared end 11. Asvhns lier-ctofore been stated, the scid upper ihn-ed end 'lil residing n t i of the stack is inclosed in a hood and this hood is iorined oi two sections, the lower section benifbr indicated in general by the reference character A and the .upper section by the reference character B. The lower section A is secured directly to the stack and has its body portion 12 of the same general outline as the llared upper end of the stack,

the woll ol the body portion and the wall of r the flared upper end of the stack be'ng spaced with respect to euch otherand t e upper edge of the section Ai being terininated n1 a horizontal plane with the upper edgeof the flared upper end 11 of the stack 70 und being formed wit i a l'lnnge 13. The u iier section B ol. the hood is substantially lrusto-conicel in shape und is formed at its lower edge with a ihiiige 14 which is disposed against the flange 13, there being bolts 15 75 passed through the two ilanges pose of securing the upper section B in position upon the lower section A ol the hood.

A delimiter 16, which is substantially of l'or the purinvertcd liusto-coiiical torni, is secured et its upper or niiijor end to the wall ol the upper section B of the hood and within the said scc- C tion and is disposed with its smaller ond down, the said smaller end of the Adellectoi' being` located substantially in the sume plane es the upper odge of thc llared upper end 11 of the smoke stack. An inverted conical foraminous doilecting,r element 17 is provided rit its upper or major end with :i

threaded flange 1S which is tlirezided into u 90 similar (lungo 19 `formed ut the lower or minor end of tho dcllector 16, the conical `hnamininis dclcctin'g` element being,r in this monncr deliichnlily connected with the dellecl'or lo so that can bc removed and 95 clcniiiciil when lound necessary.

Lending fi'oiii the lower or minor end of the body l2 of the lower section A of'the hood and extending downwnrdly clon(T opiositc sides ol' the smoke slack l() are cinder 100 l i'zolleifting and discharge i n bes 20, tothe lower ends of which aro hinged doors 2]. which may be swungr upon their hinges to permit of discharge of the cinders from 'the said pipes, it

beinVr understood that the ciiiders ere di- 10 roctcd against thil'oraininous und the impor-lernte dellcctors i7' und 16 res ectively nud downwnrdly between the wullb of the llared upper ond 1l of the smoke stock and thc lower section A ol the hood inclosing the lilo szinic, and that the said cinders settle intothe`4 pipes 20 und collect therein vuntil such tirneA tlon B of the yhood in a plane above the deof the upper section as the doors 21 are opened, the doors being normally held closed by means of suitable latches 22. The smoke, freed of the sparks and cinders,passes through the foraminous delector 17 and out through the upper end B of the hood.

Forme at diametrically opposite points through the Walls of the lower section A of the hood are openings 23 which are covered by sheets of foraminous material 24, these coverings preventing sparks and cinders being dischar ed from the openings but permit ting of dra t through the o enings to aid in the establishment of a circulation Within the stack and hood. In order that the size of the openings 23 in the lower section A of the hood may be varied according to the fuel used and its condition, imperforate slides, preferably of sheet metal, indicated by the numeral 25, are arranged for movement into osition to close or to expose the said openings 23, these slides being of course arranged u on the outer. side of the said section A so t at they may openings or vents 26 are formed in the secflector 16 and these vents also aid in the es- .tablishment of a circulation Within the hood and stack.

What is claimed, is

1. The combination with a smoke stack having an inverted frusto conical mouth, of a be moved by hand. Similar i l hood over the mouth thereof, an inverted i frusto conical deflector in the hood above the i mouth of the stack, a thriiiaded cylindrical :"7

portion formed on the lower end of said dei Hector, and an inverted conica-l strainer pro i vided with a threaded riin adapted tobe, held in the threaded portion of the deilector, said `strainer having its sides parallel with the i mouth of the stack.

i 2. rhe combination with a slnohe stack ha 'ng an inverted frueto conical nwuth and a sectional hood having an inverted 'rusto conical lower portion i mouth and a frusto conical upper portion eX- i tending thereal'iovc the stack, an imperforate dellector of inverted frusto conical shape arranged Within the upper section of the hood over the, mouth of the stack, a threaded cylindrical flange on the lower end ol" said deilector, and an invert-ed conical strainer provided at its upper end with a threaded rim adapted to engage the threaded llange oi` the delleetor, strainer, mouth of the stach, and the lower i portion of the hood being parallel.
